Pistol specifically or handgun in general?
If a general handgun, I like the Smith 25-2. It's extremely accurate and pointable, especially with the 6" barrel.
If not a revolver, there really isn't another non-M1911 .45acp semi-auto handgun that I like. They're all too big for my hand, are double action (which I hate), or some combination thereof.
I like Glocks, but the standard Glock 21 is too big for my hand, and I've never had the opportunity to hold a 21SF, much less shoot one.
There's an outside possibility that the M&P .45 MIGHT work, but I've never shot one. I may or may not have held one at a show. The FN FNP .45 MIGHT have been a reasonable size, but is double action. If the FNS comes in .45 it might work.
